Hi!
We bought a module var som om37 (DM3730 + PowerVR SGX 530 + WINCE 7)
We have a problem with render data with OpenGL ES 2.0. When we draw a data (lines), PowerVR crashes after few hours. After crash we need to restart module.
We've got soft for drawing from "Imagination Technologies" official site and changed in source code only data for drawing. We didn't change a initialization or draw calls in example.
We are using Windows Embended Compact 7 with PowerVR driver version: 1.7.17.4352 TI:U7011. SGX Core revision in OSDesign - 1.25.
We have got a error log. Most of the log takes a message:
PID:04560002 TID:04580002 PVR: GrowPerContextPB: PB Limit reached (1000,sgxpb.c)
And then follows an Data Abort.
We allocate a two static buffers and when I draw a single buffer, I update the data in the other. Data update occurs a 3-4 times per second.
Imagination Technologies support said to us, that the problem is in Parameter Buffer. They said when Parameter Buffer has filled, driver must handle this scenario gracefully with a minor performance hit, but it seems that there is a bug in target's driver which is causing a crash when this event occurs.
Can you help us with this problem?
Thank you!
